Abstract: PURPOSE: A polarizing plate and a liquid crystal display including the same can have about the same transmissivity and mechanical strength as triacetyl cellulose film and can reduce manufacturing costs. CONSTITUTION: A polarizing plate (11) comprises a polarizer (21), an optical compensation film (27), a thin film layer (24), and a coating layer (26). The optically compensation film is positioned in the top of the polarizer, and an upper polarizing plate locates a release film attached on a liquid display panel. A thin film layer transmits light polarized by the polarizer and has an in-plane phase difference value of 500 through 3000nm. A coating layer has anti-glare property of 35% to 15 and includes multiple anti-glare particles having different refractivity.

Abstract: PURPOSE: A polarizing plate and an organic light emitting device including the same are provided to improve the light loss of blue emitting spectrum. CONSTITUTION: A phase difference film (30) is formed at one side of a polarizing film (20). A protection film (10) is laminated on the other side of the polarizing film. The protection film uses a reflection preventing film, a low refraction rate film, and a hard coating film. The polarizing film has transmissivity of 0.95 to 1.1. The phase difference film controls phase difference or has view angle improving function by controlling the optical property of lights. The phase difference film varies linearly polarized light to circularly polarized light or circularly polarized light to linearly polarized light by granting a phase difference as much as λ/4 to two polarizing elements which are mutually perpendicular and parallel to the optical axis of phase difference film as a λ/4 phase difference film.
